read_csv operator transforms csv files into Tercen datasets. It can upload an individual CSV file or multiple CSV files in a zipped folder.
CSV files (.csv) are text files which use a comma as the delimiter.
(Tercen also has a 'Delimited text' file importer with settings for both comma and other delimiter types. It has more advanced features for data maipulation but cannot be embedded as a file importer in a workflow.)

The operator transforms a csv file into a Tercen table. If the document is a ZIP file containing a set of csv files, the operator extracts the csv files and transforms them into Tercen table.
